If you find your ball in the woods, it is unplayable. If a professional finds his ball in woods, not only is it playable but he can hit it onto the green.

Sam and Harry are playing one day. On the first hole, Sam hits a wicked slice into the adjoining fairway. The ball hits another player right between the eyes and he drops to the ground.
Sam and Harry rush over to the prostrate man and find him unconscious with the ball laying on the ground between his legs.
Sam screams, "Oh my God, what should I do?"
Harry replies; "Don't move him. If you leave him there he becomes an immovable obstruction and, according to the rules, you are allowed a drop two club-lengths away."
One of the most common faults people make with putting is that they look far to early to see if they have holed the putt or not.
This will cause the shoulders to open and the legs and hips will also move when they should remain still.

You should also have one or two practice strokes before you hit the ball this will give you a better feeling for the length of putt, the eyes should also be positioned over the ball at the address position, this will enable you to see the line of the putt better.
A good tip is once you have struck the ball, count in your mind to 1 and them look to see where the ball is going, this will help your hips and legs to stay still and your shoulders will remain more square to the target.

I will guarantee that you will control your distance much better for the longer putts and you will also hole a lot more shorter putts.
